The Duffer brothers haven't said when Stranger Things season 4 will premiere, so we'll just have to wait a while longer for an official announcement. For the first 40 seconds or so, we watch the camera slowly pan in on a group of workers in Russian Federation building a railroad. However, when a post-credits scene in the finale revealed that the Russians had kidnapped "an American" without specifying which American, many fans became convinced that Hopper was the American in question and was, thus, still alive. Among the laborers is Hopper - alive and well. And as it turns out, those viewers guessed correctly. But Hopper's body (dead, alive, whatever) was never shown, leaving the possibility of his return in the air.
"He is imprisoned far from home in the snowy wasteland of Kamchatka, where he will face dangers both human. and other", the Duffer brothers' statement said, according to The Hollywood Reporter.
When season three ended, the Stranger Things showrunners had everyone believe that Hopper had died.
With the return of Hopper comes even more theories, the best - and the one gaining the most traction on Twitter - being a Stranger Things-MCU (Marvel Cinematic Universe) crossover.
Season 4 is shaping up to be the biggest and most frightening season yet, and we can not wait for everyone to see more. The camera closes in on one of them as he takes off his woolly head covering to reveal himself to be Hopper, looking more emaciated than when we last saw him, but even more disgruntled.
